Abstract
Abstract A motion picture camera wherein the housing is pivotally connected to a hollow pistol grip handle and accommodates one or more current-consuming units, such as an electric motor for the shutter and pulldown and an exposure meter. The handle accommodates a removable container with a set of batteries which are connected in circuit with the exposure meter and/or motor when the handle is pivoted to operative position in which terminals provided on the top wall of the container engage complementary terminals on the bottom wall of the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
In a motion picture camera, a combination comprising a housing having a bottom wall; at least one current-consuming unit installed in said housing and having first electric terminal means locAted in the region of said bottom wall; a hollow handle having an internal compartment including an open upper end; mounting means permanently mounting said handle on said housing for pivotal movement between an operative position in which said upper end of said compartment is adjacent to the bottom wall of said housing and an inoperative position in which said handle is pivoted away from said operative position and said upper end of said compartment is readily accessible; and means for supplying electric current to said unit, including at least one source of electric energy and second electric terminal means connected with said source of electrical energy, said means for supplying electric current being removable from and reinsertable into said compartment by way of the upper end of said compartment in the inoperative position of said handle and said second terminal means being moved into current-conducting engagement with said first terminal means in response to movement of said handle from said inoperative to said operative position thereof and remaining in such current-conducting engagement while the handle dwells in said operative position.

In a motion picture camera, a combination comprising a housing having a bottom wall; at least one current-consuming unit installed in said housing and having first electric terminal means locAted in the region of said bottom wall; a hollow handle having an internal compartment including an open upper end; mounting means permanently mounting said handle on said housing for pivotal movement between an operative position in which said upper end of said compartment is adjacent to the bottom wall of said housing and an inoperative position in which said handle is pivoted away from said operative position and said upper end of said compartment is readily accessible; and means for supplying electric current to said unit, including at least one source of electric energy and second electric terminal means connected with said source of electrical energy, said means for supplying electric current being removable from and reinsertable into said compartment by way of the upper end of said compartment in the inoperative position of said handle and said second terminal means being moved into current-conducting engagement with said first terminal means in response to movement of said handle from said inoperative to said operative position thereof and remaining in such current-conducting engagement while the handle dwells in said operative position.
Claim 3
Dependent Claim
59 words
A combination as defined in claim 1, wherein said means for supplying electric current to said unit further comprises a container having a top wall in the region of the open end of said compartment, said source of electrical energy being located in said container and said second terminal means being provided on the top wall of said container.
Claim 4
Dependent Claim
50 words
A combination as defined in claim 2, wherein said current-consuming unit comprises an electric circuit having switch means movable between open and closed positions, said container comprising actuating means for moving said switch means to one of said positions in response to movement of said handle to said operative position.
Claim 5
Dependent Claim
15 words
A combination as defined in claim 3, wherein said current-consuming unit is an exposure meter.
Claim 6
Dependent Claim
20 words
A combination as defined in claim 2, further comprising resilient retaining means for releasably holding said container in said handle.
Claim 7
Dependent Claim
21 words
A combination as defined in claim 1, further comprising resilient retaining means for releasably holding said handle in said operative position.
Claim 8
Dependent Claim
35 words
A combination as defined in claim 1 wherein said housing contains a plurality of current-consuming units and said means for supplying electric current comprises a plurality of energy sources, one for each of said units.
Claim 9
Dependent Claim
42 words
A combination as defined in claim 7, wherein one of said units comprises normally open switch means and said means for supplying electric current comprises means for closing said switch means in response to movement of said handle to said operative position.
